An extract from the top portion of the third MGS-Cydonia strip image taken
April 23. This shows a set of embedded triangular features. Triangles are rare
phenomena on moon and planet surfaces except at Cydonia, where many triangles
and other features composed of linear sections are seen.

An extract from the top portion of the third MGS-Cydonia strip image taken
April 23. This shows an unusual feature with dark stripes or bands. The feature
is a few hundred meters long, and somewhat resembles a large lizard. Material
sliding down the smooth pyramid-like face behind this object has been suggested
as a possible natural explanation. We show it here because, just above
(behind?) the dark stripes is an almost identical set of fainter dark stripes,
as if a reflection were being seen. Likewise, irregular shapes to the right
along the base of this smooth face also have fainter (mirror?) images "behind"
them. If these were reflections, the presence of manufactured materials such as
glass or metal would be implied.

This shows the triangular
eyebrow feature just above the west eye socket on the Face. All three sides are
apparently linear, and the bright portions are apparently on a front section
facing directly into the Sun.

Mark Carlotto's ortho-rectified view of the Face. This uses height information
from the Viking photos to reconstruct how the Face mesa would appear if viewed
right-side-up from above. Naturally, only features on the visible west side are
present in this image. East-side features were hidden behind the nose ridge and
are therefore nearly blank in this rectified view.

If we make the assumption that the east side is a mirror image of the west
side, this is the resulting rectified view. Only east side information was
inserted; while the west side is still identical with the rectified view above.
If we take this view and ask the computer to reconstruct what we would see from
a 45-degree west viewing angle with sunlight eliminating contrast for
illuminated east-side features, we would arrive at an image rather similar to
what MGS actually saw. (Of course, an east-side that was not symmetric would
also work. This merely shows that perfect symmetry is consistent with both
Viking and MGS data.)
